Discovery of 9-phenylacridinediones as highly selective butyrylcholinesterase inhibitors through structure-based virtual screening
(Elsevier, 2020)Butyrylcholinesterase (BuChE) is considered a promising drug target as it plays an important role in the pro-gression of late stage Alzheimer’s disease (AD). Two compound libraries were selected and 64 124 aminecontaining ... -
Discovery of a filamentary synchrotron structure connected to the coherent magnetic field in the outer galaxy
(The Astrophysical Journal, 2023)Using data from the Galactic Arecibo L-band Feed Array Continuum Transit Survey, we report the discovery of two previously unidentified, very compressed, thin, and straight polarized filaments approximately centered at ... -
Discrimination of tomato plants (solanum lycopersicum) grown under anaerobic baffled reactor effluent, nitrified urine concentrate and commercial hydroponic fertilizer regimes using multi-source satellite data
(ISPRS, 2019)We evaluate the detection and discriminative strength of three different satellite spectral settings, namely, HyspIRI, the forthcoming Landsat 9 and Sentinel 2-MSI, in mapping tomato (Solanum lycopersicum) plants grown ... -
Discrimination of tomato plants (solanum lycopersicum) grown under anaerobic baffled reactor effluent, nitrified urine concentrates and commercial hydroponic fertilizer regimes using simulated sensor spectral settings
(MPDI, 2019)We assess the discriminative strength of three different satellite spectral settings (HyspIRI, the forthcoming Landsat 9 and Sentinel 2-MSI), in mapping tomato (Solanum lycopersicum Linnaeus) plants grown under hydroponic ... -
Disentangling non-gaussianity, bias, and general relativistic effects in the galaxy distribution
(American Physical Society, 2012)Local non-Gaussianity, parametrized by f NL , introduces a scale-dependent bias that is strongest at large scales, precisely where general relativistic (GR) effects also become significant. With future data, it should ... -
Dispersal and coastal geomorphology limit potential for mangrove range expansion under climate change
(Wiley, 2022)Latitudinal range limits for mangroves on high-energy, wave-dominated coasts are controlled by geomorphological features and estuarine dynamics. Mangroves reach a southern global range limit along the South African ... -
Dispersal and coastal geomorphology limit potential for mangrove range expansion under climate change
(John Wiley and Sons Inc, 2022)Latitudinal range limits for mangroves on high-energy, wave-dominated coasts are controlled by geomorphological features and estuarine dynamics. Mangroves reach a southern global range limit along the South African coastline, ... -
Dispersal dynamics of SARS-CoV-2 lineages during the first epidemic wave in New York City
(Public Library of Science, 2021)During the first phase of the COVID-19 epidemic, New York City rapidly became the epicenter of the pandemic in the United States. While molecular phylogenetic analyses have previously highlighted multiple introductions and ... -
Dissemination and survival of non-indigenous bacterial genomes in pristine Antarctic environments.
(Springer Verlag, 2005)Continental Antarctic is perceived as a largely pristine environment, although certain localized regions (e.g., parts of the Ross Dependency Dry Valleys) are relatively heavy impacted by human activities. The procedures ... -
Disturbed, diffuse, or just missing? A global study of the H I content of Hickson compact groups
(EDP Sciences, 2023)Context. Hickson compact groups (HCGs) are dense configurations of four to ten galaxies, whose H I morphology appears to follow an evolutionary sequence of three phases, with gas initially confined to galaxies, then ... -
The diurnal activity budgets of extralimital giraffe (Giraffa camelopardalis giraffa) in the Western Cape Province, South Africa
(Wiley, 2023)Despite being an extralimital species in the region, South African giraffes (Giraffa camelopardalis giraffa, Schreber 1784) are continuously being introduced into the Albany Thicket Biome of the Western Cape Province of ... -
Diurnal variations in global Joule heating morphology and magnitude due to neutral winds.
(Wiley, 2018)In the polar ionosphere, variations in Joule heating are significantly controlled by changes in plasma convection, such as that brought about by changes in the interplanetary magnetic field. However, another important ... -
A diverse array of genetic factors contribute to the pathogenesis of Systemic Lupus Erythematosus
(Biomed Central, 2013)Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune disease with variable clinical presentation frequently affecting the skin, joints, haemopoietic system, kidneys, lungs and central nervous system. It can ... -
Diverse genomoviruses representing twenty-nine species identified associated with plants
(Springer Nature, 2020)Genomoviruses (family Genomoviridae) are circular single-stranded DNA viruses that have been mainly identifed through metagenomics studies in a wide variety of samples from various environments. Here, we describe 98 genomes ... -
The diversity and variability of star formation histories in models of galaxy evolution
(2020-07-25)Understanding the variability of galaxy star formation histories (SFHs) across a range of time-scales provides insight into the underlying physical processes that regulate star formation within galaxies. We compile the ... -
Diversity of dsDNA viruses in a South African hot spring assessed by metagenomics and microscopy
(MDPI, 2017)The current view of virus diversity in terrestrial hot springs is limited to a few sampling sites. To expand our current understanding of hot spring viral community diversity, this study aimed to investigate the first ... -
DNA commission of the international society of forensic genetics (IGSF): recommendations on the interpretation of y-str results in forensic analysis
(Elsevier, 2020)Forensic genetic laboratories perform a large amount of STR analyses of the Y chromosome, in particular to analyze the male part of complex DNA mixtures. However, the statistical interpretation of evidence retrieved from ... -
DNA sequencing reveals three new species of Chamberlainium (Corallinales, Rhodophyta) from South Africa, all formerly passing under Spongites yendoi
(De Gruyter Open Ltd, 2021)Three new non-geniculate coralline algal species from South Africa are described that were passing under the misapplied name, Spongites yendoi. Based on plastid encoded DNA sequences from psbA and rbcL markers, these species ... -
Do HIV infection and antiretroviral therapy influence multidrug-resistant tuberculosis treatment outcomes?
(Academic Journals, 2015)The aim of this study was to find out whether human immunodeficiency virus (HIV)-infection and antiretroviral drugs influence multidrug-resistant (MDR)-tuberculosis (TB) treatment outcomes. The study compares MDR-TB treatment ... -
Do lifestyle practices impede male fertility?
(John Wiley & Sons, Inc, 2020)Alongside an increasing prevalence of couple and male infertility, evidence suggests there is a global declining trend in male fertility parameters over the past few decades. This may, at least in part, be explained ...
